“…Given the requirements of high reliability and low cost in developing power grid systems, the concept of microgrid is proposed to realise large-scale energy conversion and power transmission through resource optimisation (Tripathi et al, 2020). The microgrid system takes advantage of the two-way flow of power and information to achieve realtime demand-supply regulation in a consistent, secure and efficient manner (Fang et al, 2011;Hau et al, 2013;Mocanu et al, 2016;Sun et al, 2011).…”

The communication system of a microgrid can transfer the information of electricity price, power consumption and so on between users and the control centre. This capability is of great significance to improve the efficiency and sustainability of power facilities. In this paper, a bidirectional DC–AC converter topology is proposed to achieve the composite transmission of power and signals in microgrids. Since the transmitted signals are modulated by power switches of converters and integrated into the currents, the cost of signal couplers can be saved and the circuit structure can be simplified. In order to verify the feasibility of the proposed method, a simulation model of the proposed converter is implemented in MATLAB/Simulink. With the power supply frequency of 50 Hz, when the converter operates in the inverter mode and rectifier mode, the data transmission rate can reach 120 bit/s and 48 bit/s, respectively.
